Product details
Description
Even if you’re not a die hard Dead Head, you’ve almost certainly seen this friendly fivesome before. First appearing on the back cover of the 1973 album History of the Grateful Dead, Volume One (Bear's Choice), the Dancing Bears* have stuck around as a staple of music iconography for 50 years. And just like the music of the Dead will never stop, we’re pretty sure the Dancing Bears aren’t going anywhere anytime soon.
Built to last on the fan-favorite Fort Knocks, this prescription pair lets you bring some tie-dye Dancing Bears cheer along no matter where you’re headed!
*If you talk to a purist, they’ll tell you the bears are marching, not dancing. But like thousands of other Deads Heads already have, we’re happy to encourage alternative interpretations.

Sustainability
In 2022, Knockaroud officially became Plastic Neutral—for every pound of plastic we use, we remove one pound from the environment elsewhere. But that’s far from where our sustainability efforts end. We’ve also implemented minimalist, recycled packaging, eliminated single-use plastics, and included recycled materials in our products whenever possible. There’s always more progress to be made, but we’re committed to putting in the work.
